This dataset represents expert-validated occurrence records of calling frogs across Australia collected via the national citizen science project FrogID (www.frogid.net.au). FrogID relies on participants recording calling frogs using smartphone technology, after which point the frogs are identified by expert validators, resulting in a database of georeferenced frog species records. This dataset represents one full year of the project (10 November 2017-9 November 2018), including 54,864 records of 172 species, 71% of the known frog species in Australia. This is the first instalment of the dataset, and we anticipate providing updated datasets on an annual basis.
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 126,169 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Launched on 10 November 2017 and led by the Australian Museum, FrogID is the first citizen science initiative aimed at capturing validated biodiversity data on Australian frogs on a national scale (Rowley et al. 2019). The FrogID project collects data via a smartphone application allowing participants to submit recordings of calling frogs, which are then identified to species by experts (Rowley et al. 2019).
|Funding||Funding for the FrogID project was provided by the Australian Government’s Citizen Science Grants program, the Impact Grants program of IBM Australia provided the resources to build the FrogID App. In-kind funding was provided by the Australian Museum. Bunnings and Fyna Foods are project partners.|
The personnel involved in the project:
FrogID collects data via a free smartphone app (iOS and Android). Recordings are 20-60 seconds in MPEG AAC audio (mp4a) files. The time, date and geographic location (latitude, longitude and an estimate of precision of geographic location) are automatically added by the app at the time of recording. Each recording has an estimate of precision and, depending on the question, these records may influence results. As such, for records that rely heavily on geographic precision, we recommend filtering to records which have an estimate of geographic uncertainty of < 3000 meters. After recordings are submitted, they are stored in a cloud-based Content Management System (CMS), before being validated. FrogID validators, experts in identifying frog species by their calls, then use the audio and associated information, plus a reference call library, to identify the frog species calling in the recording. One submission can have multiple frog species calling within it. After these processes, we are left with a presence-only dataset of frog species in Australia. For a more detailed overview of methodology and design aspects see Rowley et al. (2019).
|Study Extent||FrogID submissions have come from across Australia but, not surprisingly, are biased towards populated areas, with large areas of Australia, particularly in remote areas, lacking FrogID records. Despite this bias, the spatial coverage of this project encompasses the continent of Australia, with frog records from 7,635,905 km2 (99%) of Australia’s landmass (measured as a minimum convex polygon enclosing all occurrences, excluding ocean).|
